Manchester City duo Joe Hart and Vincent Kompany have been going the extra mile in the gym as they aim to make fast recoveries from their respective injuries.

Manuel Pellegrini and City supporters alike will be hoping Hart and Kompany are back in action shortly after the international break as their side's games come thick and fast in the Premier League and Champions League.

Hart has been forced into sitting out England's two friendlies against Germany and Holland, while Belgium skipper Kompany will miss his country's encounter with Portugal in Leiria.

Despite concentrating on his recovery from injury, Hart found time to send a good luck message to stand-in England captain James Milner ahead of Tuesday night's encounter at Wembley Stadium.

'Me and the skipper on the comeback trail... And good luck to CAPTAIN MILNER tonight. #cmonengland,' Hart said on his official Instagram account.

The 28-year-old goalkeeper is expected to miss Manchester City's upcoming Premier League clash with Bournemouth after picking up an injury against rivals United before the international break.
